[s-cars] Fuel Odour from Under Car

[Fred Munro]

Sean;

The fuel lines corrode and leak under the rubber line mounts. Dry the area
off and take a look with the car running - you may have a line that only
leaks under pressure. As a preventative measure every UrS owner in the rust
belt should pop the mounts off the fuel lines, remove the rubber blocks, and
clean, paint, and spray the lines with your favourite anti-rust treatment
before re-installing the mounts. If you don't your fuel lines will fail, in
spite of Audi's lovely epoxy-coated, copper-clad steel fuel lines.

Subject: [s-cars] Fuel Odour from Under Car


For the last 2 weeks, I've noticed a strong fuel odour in the garage
after I park the car. I traced the fuel lines in the engine bay and
couldn't find any visible signs of gasoline - no odour either.

Today when I was washing my car (balmy 12 celcius), I noticed the smell
at the right rear, just ahead of the rear wheel. I jacked up the rear
and took a look at the fuel lines. There are 3 lines, supply, return and
evap (I think). There is a black plastic cover and above this, are
several connections where the hard lines change to flex lines. Some are
clamped, others have a threaded fitting. No sign of gasoline here
either, but the odour was unmistakably gasoline - hard to tell because
this area was wet with water.

Since there is an odour, but no sign of fuel leads me to believe it has
something to do with the evap system?

I think I should take a closer look when its dry - any tips or
suggestions?

Thanks,
